c4th: Thanks! about the Keyshot Tutorial, on each model I use different setting so would be hard to make just one single tut which covers all the scenarios, let me know about what are you interested in and I will show you my tricks 
lstdragon: Thank you! glad that you’ve found what you were looking for, I’ll try to help you…
About the questions:
1- I only use Zbrush, no any other CAD software, based on my experience I have learnt my workflows to don’t depend of other software, Zbrush is fully capable.
2- I set all measurements with Transpose Line and Zplugin 3D Print Exporter
3- Yees, as mentioned, 3D Print Exporter (comes as defaut plugin) and Dynamesh Master, determinant for keep accurate Dynamesh resolution. Also I recommend you to give a try to Caliper Master: https://gumroad.com/l/CalipersMaster_FH
4- Sure! send me a private message whenever you want to talk about any course.
Thank you so much for your responses! I will definitely send you a PM and we can chat offline. Zbrush is a new program for me, so I will be in learning mode at least initially.

@ nacho riesco. the baroque skull ring is the one I’m really interested in. i would love to see how you make the interplay between enamel and metal so realistic. 
I’ll make an small tutorial about it
Halloween is coming! so it’s time for a Zbrush and Jewelry Halloween Ring, hope you like it!

Hi all! this a concept I made for a pendant, still needs to fix many things, to make it able to manufacturing, but I like to have some Keyshot fun anyway (a bit of Ps for the background)
Hi all! as promised, here is an snall tut about how to achieve the transparent enamel finishing on my Baroque Skull Ring design. As you can see it’s quite simple, just setting the material as Liquid, tweaking its Refraction and Transparency sliders, and the realistic touch, add a Bump Texture as a Fractal Noise, that’s all, hope will be useful 
P.D. Just note that is necessary to get two different pieces of geometry, you can achieve it with a mesh extraction

Thak you Jhon!
The Panther Pendant it’s a Jewelry Design inspired on Art Nuveau style, and on the great illustrations from Alfons Mucha.
It’s composed by three parts, circular frame, inner curves and the panther, which can be printed and casted separately, for the subsequent finishing and polishing work. It has 40 mm of diameter and 4,5mm width.
Hope you like it!
